MINOR: http-rules: Handle the rule direction when a redirect is evaluated

MINOR: http-rules: Handle the rule direction when a redirect is evaluated

The rule direction must be tested to do specific processing on the request
path. intercepted_req counter shoud be updated if the rule is evaluated on the
frontend and remaining request's analyzers must be removed. But only on the
request path. The rule direction must also be tested to set the right final
stream state flag.

This patch depends on the commit "MINOR: http-rules: Add a flag on redirect
rules to know the rule direction". Both must be backported to all stable
versions.
